Specification of `Letters Patent.

Patented Feb. i0,V 19E/tf application filed october is, ist?. serial No. season.

To all whom t may conce/m:

Be it kno-Wn that I, Trimmer E. BRAND, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful lmprovements in lVlatrix-SelectM infn' Mechanism; and l. do hereby declare the proper order for composition.

lt is designed especially to enable the use of a larger number of characters inthe font of matrices, type or dies than has been possible heretofore and at the same time to reduce the Width of the controller-at least relative to the 4number of characters; 'also to provide a matrix-placing mechanism in which the Avari-ably moving parts are positive at all times.

With a rectangular form of matrix case it has not been found practicable to provide lfor more than Q25 characters (l5 rows with l5 matrices iny each row.) lfn the U. S. Letters Patent No. 862,800, granted to, me Aug: 6, 1907, l showed a term of matrix case by means of which l have been able to increase this number somewhat. ln that machine the matrix case had a circular`sliding movement tofselect a matrix bar and the Whole case was moved bodily to select the particular matrix of that bar. ln my improved machine I use the same form ofcircular sliding movement to select the bar, but instead of moving the Whole case, l move only the selectedbar, in order to secure the selection of the particular matrix Wanted. Furthermore l have provided a variable speed dev-ice, under the action of the controller, whereby, when the outlying bars or those requiring long movements are to be selected and the characters on the selected bar reql'iiring longmovements are Wanted,

. the speed of the machine is reduced. W' ith this term of matrix case and by using` a vhriable speed device l am able to put in from six to eight hundred characters or even more.

ln order'that the controller may not be unduly Wide, I have provided a-compound selecting device, by' means of which a. small number of actuating pins in the controller will secure the selection of a large number of characters.

Other improvements will be described in the specilication and pointed out in the claims. .I I'

ln' thefollowing description reference is made to the accompanying drawings in which:

Fig. 13 isl a detail showing a portion of the speed cl'ianging de ice My improvements Were designed especially for use in connection with a typecasting and composingl machine such as is shown and described in my former patent, above referred to. l have illustrated and Willl describe only so much of a machine as lwill be necessary for a full understanding `-of my improvements. `l have, therefore, not

deemed it necessary to show a key-board, or any means for setting the actuatingmins of the controller. The unit registering and justifying lmechanism is also omitted; also the means for setting the body piece of the mold, as well as the melting pot and metal lnjecting` mechanism and means for removy ing the type from the mold and assembling the same in agalley. A y

Bez/ail descriptiom-The matrix-case is mounted above a plate l. This plate is supported on top of a hollow, substantially square column 2, which has a suitable base 3; The matrix-placing mechanism is located at the right of the column.. A shaft 4 mounted vin the front and-rear Walls of the column,

-another without danger or tendency of carries the cams from which the various i automatic movements necessary to drive the i various parts are generated, The matrixi case is composed of matrix bars 5 (see Figs. 5 and t3.) rthese bars have flanges or ears li, at their Ifront and rear ends7 by means ci which they are supported in annular grooves ".7, in 'front and rear plates 8 and 9 respectively Underneath the case, mounted on a suitaole mold base 10, is located the mold, composed ot left and right cheek pieces l1 and 1Q respectively; cover slide 13; body piece 14. These being the names in common use among type founders the 'function and use of the parts are well understood. On the top oft' the mold there are two alining plates which form an alining slot 16 into which one of the matrix bars 5 may be impressed in order to seat one of the matrices 17 on the mold.

Extending from front to rear, between the plates 8 and 9, there is a vertically recipro eating impression bar 18, connected by a pair of links 19, to a pair of arms 2G, which are on a shaft 21, rlhis impression bar 18 carries a T-shaped rack 29- mounted in a slot 23 oi' the said bar. rlhis rack has a pair of downwardly projecting hooks 24 which when the bar is in its normal or central position7 exactly aline with the annular grooves 7. These hooks are adapted to support the matrix bar which is directly over the alining slot.

The matrix case is given a rotating move ment by rocking a shaft 25. rlhis shaft is mounted in the iront and rear plates and has a pair of arms 26, which carry a semi-cylin drical plate Q7. This/plate comes against the outside matrix bars and, together with the bars7 forms virtuallya complete cylinder. lt will be 'noticed that the matrix case is in the form of a sector of a regular right prism, whose axis is the center of the shatt- 25 and that the twenty seven bars shown occupy an arc of a little over one hundred and eight-y degrees-requiring a movement of a little over ninety degrees to bring the most distant matriz bars in posit-ion over the alining slot 16.

The matrix bars are slightly concave on their inner surface-being made to the radius of the matrix case and a portion of the sides of the bars (that opposite the iianges) are made radial, as -shown in Fig. 7. rlhis arrangement permits one bar moving cramping.

The shari,

is rocked in eit'ier t irectien by means ei' Ys Vailier a matrix bar has been se1 and mounted on the left end of aI shaiit E33; said shaft having a bearing near its lethan l end in a plate 34. This racif and are cut spil-ally for a purpose which will appea later.

After a matrix has heen sll cted and brought to the impression pont it seated in the alining slot on the mold by rocking the impression shaft QL- Ylhis is accomplished from a cam 8G located on the shaft 4 just outside the column 9., through the following connections: roll 37; lever 38; connecting rod 39; impression arm 40. This movement carries the rack teeth 31 of the rack Q2 out of mesh with its gear 3:2', or partly so and as the rack 29. is moved downward a centering pin 41, mounted on a brac ret 42, enters one of a series of holes 48 in the raclr The centering pin locks the'raclr 22 so as to secure the proper position for the selected matrix.

iloLrz'-seleotz'ng 'HLeULaM'SWL-Jt is evin dent from the foregoing description that, by

reciprocating the rack 28 and by revolving 9 the shaft 33, any desired matrix in the case may be brought to the impression point- 35. Thesel movements are accomplished by mechanism located at the right of the machine and mounted in a housing composed of front and rear plates 44'and 45; lett and right plates 46 and 47; top and bottom plates 48 and 49.

There is a vertical slide 50 which has, near its center, a pair of arms 51 in which there is a horizontal row of nine selecting pins The slide 50 has rack teeth 53 which are in mesh with a gear which is on a short shaft said shaft having a bearing. in a boss 5G on the inner side or" right hand plate 47. On the front end of this shaft is a gear 57 which is in mesh with a rack .5S-said rack being mounted to slide in a slot cut in a projection, 59 which is on the rear side offrent' plate 44.-,heing held in position by a tongueV 60 which enters a groove 61 in said rack, The left hand end of the rack 58 has an upwardly extending portion which carries a short shat't. On the front end of this shaft is a vertical arm G3 which is connected by a pin 64 to the rack 28. rlhe rear end of the shaft 62 has a horizontal arm 65, the right hand end of which has a rearwardly projecting pin G6 which enters a slot. 67 ma cross-head 38; V

said cross-head being mounted to a vert-ically sliding bar 69. This bar has two selecting pins quite similar to pins 52. From this construction it is evident that as the slide is moved upward downward normal movement ot the rack 22.

the rack 58 will be moved to the right or pin 52 is driven no motion will be impartedl to the slide 50. If pins to the right of the center are driven the slide 50 will be carried upward varying distances according to the pin driven. If pins to the left of the center are driven the slide will be carried downward varying distances according to the pin driven. Nine positions of the slide 50 are thus secured which will select, through the parts pointed out, nine of the twenty seven matrix bars 5-that is every third ba'r (represented in the drawings Fig. 5 by radial shading.)

By moving the slide 69 a` supplemental movement is imparted to the rack 28, increasing or decreasing' it, according as the movement ot' the bar 69 is upward or downward; so that instead of selecting one of the nine bars referred to, it will select one of the adjacent bars. From this construction it is evident that the nine positions of the slide 50, in combination with two movements of the slide 69, are capable of selecting any one of the twenty seven matrix bars.

At the left of the slide 50 and .mounted in the same plates is a similar slide 71, having tive selecting pins 72. This slide has a spiral rack 73 in mesh with a gear 74n which gear is located or. the right hand end of the shaft 33-said shaft havingl its right hand bearing in a boss 75 extending to the right from the lett hand plate 46. The shaft 33 has, just outside the plate 46, a pair ot collars 7 6. These collars inclose a roll 77 which is carried by an upwardly extending arm of a bell -crank 78 which bell crank is mounted on a hanger 79 on the .left hand side. plate 46. The horizontal arm 78 ot' the bell-crank is connected by a link 80 to a vertical slide 81. This slide is mounted alongside of and is similar to slide 69 and has two selecting pins S2. As the slide 71 is carried upward or downward t which movement is effected in a manner similar to that ot slide 50 to be explained) the shaft 33 is turnedand, through the parts already pointed out, the rack 22 will take any one of tive positions. This will secure the selection of the. central matrix of the bar and every third matrix therefrom. 4

The rack and gear 7.) and 74 are lett hand spirals, while the rack and gear 3l and 32 are right hand spirals. By moving the slide 81 upward or downward the shaft 33 is given a movement lengthwise in its bearings and a sxuliplemental movement obtained thereby which increases or decreases the This secures the seleciionof the adjacent matrices and"'^i't is evident that by means of the tive positions ot' the rack 7l and two movements of the slide 81, any one of the 15 matrices of a matrix bar may be selected and brought to theimpression point.

In thus compounding the movements ci the selecting devices, as above described, by the use of supplemental feed movements, l am able, by eight variable movements of the slide 50; four movements of the slide making a total of sixteen movements-41o secure the selection of all of the vtour hundred and live matrices of the case. By two additional pins 72 in the slide 71, matrix bars containing twenty lfive matrices might be used and the total number of matrices increased to six hundred seventy live. By the use of two additional pins 52 in the slide 50 eighteen extra matrix bars could be used-liltewise increasing the number of matrices. By using two extra pins 52 and two extra pins 72 at the same time, the number of matrices in the case could be increased to one thousand one hundred and twenty-live. l

Each selectingr pin requires a single representation oractuating pin in the controller as will appear later. By the above arrangement I am, therefore, able to use a narrow controller and yet select any one of a large number of matrices of the case.

Placer sZz'des.-At the rear of the slide 50 is a series of placer slides 88, 84, S5, 86, 87, 88, 89, 90 separated by a stationary center piece 91. These slides are mounted for vertical movements in the base plate 49 and in a slotted piece 92. Each slide is connected by a link 93 to a lever 94. This lever is pivoted to a shaft 95 which has a bearing in the rear plate 45 and is held in position Iby a collar 96. The lett hand placer slide 90, ot this set, extends down through the base plate 49 and is connected by a link 97 to a horizontal lever 98 which'is fulcrunled on a rod 99 and has a roll which enters a slot in the front face of a cam-wheel 100. (This roll and cam slot are not shown but they are similar to a roll 116'and cam slot 117 which are shown and described farther on.) As the shaft al is turned the lever .()l will alternately take the position shown in Fig. 3 and the position shown by the lines l-E That is, the slides Sli-9G will he moved up from one to four steps respectively, and the slides 87-90 will be moveddown from one to `four stepsrespectively. The placer slides'S3--90 are provided with holesior sockets 101 into which the selecting pins ."2 may be driven, as will be pointed out. These sockets 101 are provided with idle pins 102 and as the selecting pins 52 are driven into their sockets the pins 102 are forced rearward. They are driven for- -71; and two each of the slides 69 and S1- y 'ward to return the selecting pins to normal position by a rocking blade 103, which is mounted between the left and right plates 46 and 47. This blade is actuated by an arm 104 which is connected by rod 105 to a lever 106. This lever has a roll 107, in contact with a cam 10S which is on the rear end of shaft -the cam-lever being mounted on the outside of the column.` At the rear of the slide 71 there are four placer slides 109, 110, 111, 112 with a central piece 113. The left hand slide 112 extends down through the base plate 49 and is connected by a link 114 to a cam-lever 115. This lever is fulcrumed on the rod 99 and has a roll 116 which enters a cam slot 117 formed in the rear face of the cam wheel 100.' The placer slides 109-112 are connected by links 118 to a lever 119. This lever is pivoted to al shaft 120 in the rear plat-e`45-similar to the lever 94 and shaft 95. As the shaft 4 is revolved the lever 119 will alternately take the position shown in Fig. 3v and the position shown by dotted line F-F, causing slides 109 and 110 to move upward one and two steps respectively and the placer slides 111 and 112 to be drawn down one and two for the slide 83 in Fig. 11.) The reciprocating movement necessary for the slides 121, 122, and 123, 124 might be generated by levers similar to 94 and 119, but I prefer to connect across by shafts and pinions as follows: The placer slide 121 is connected by pinion 125, shaft 126 pinion 127 to the placer slide 84. The placer slide 122 is'connected by pinion 128, shaft 129 pinion 130 to.v slide 88. The placer slide 123 is connected by pinion 131 shaft 132 pinion 133 to slide 110 and the placer slide 124 is connected by pin-V ion 134, shaft 135, pinion 136 to slide'112. lldrom this construction itis evident that as the lever 94 is rockedthe slides 121 and 122 will be reciprocated and as the lever 119 is rockedV the slides 123 and 124 willbe reciprocated.

.GontroZZefn-Ths consists of a series of parallel tubes 137, each tube carrying eighteen actuating pins 133 which are held in the position in which they are set by-.a friction spring 139. The tubes are pivoted together by links 1'40 which are loose on pins 141 extending from theends of the tubes.

direction indicated by the-arrow in Fig. 8,1 for obtaining two different pair of sprocket wheels 143 which are mounted on a shaft144 and it is fed, in the by a ratchet wheel 145 which is mounted on the outer end of the shaft 144. Motion is imparted to the ratchet wheel by a pawl 146 which is attached to a lever 147 which lever is fulcruined to a projection 148 from the column. The lever has, on its left end, a roll 1 49 in contact with a cam 150, by means of which it is reciprocated. pawl 151' is provided for the ratchet 145. The pins of the controller may be set up by hand or preferably they would be set by such a selecting device as is shown and. described in my previous patent already referred to.

The actuating pins 138 of the controller are caused to drive the selecting pins into their respective placer slides, by meansof intermediate horizontal slides 152. These slides are mounted on a vertically moving support 153 and are held in position by a cap plate 154. The frame 153 is mounted on a vertically sliding stem 155 and is con-- nected by a link 156 to a lever 157 which lever is fulcrume'd on the rod 99 and has a roll 156 adapted to be operated on by a cam surface 159 on the cam wheel 100.

The rear ends of the slides 152 are in front of and in close proximity to the selecting pins. vThe forward ends of the slides have downward projections 160 which, when the slides are in their lowest position, are in the paths of the actuating pins which have been set in the controller and as the shaft 144- is revolved, corresponding slides 152 are carried to the rear; thereby driving corresponding selecting pins into the placer slides. On the upward movement of the frame-153 the slides 152 will be disengaged from the actuating pins of the controller; at which time rocking blade 161, actuatedby a spring 162, will return the slides to their forward or normal position.

Variable speed lavica-When matrices are to be selected which require but a short movementi-n order to reach the impression highest possible speed. lVhen characters requiring af'long movement are to be selected I arrange' to slow. downthe speed'of the Inachine during the time these characters are being used and to restore it to its maximum speed immediately thereafter. By' this means 1 not only greatly increase the output of the machine, but I save an immense high speed. pins in the controller which go into effect at the proper time to carry the speed as may be required. able speed devices may be resorted to and several different speeds may be obtained. For the purpose of illustra-tion I have shown a variable belt driven mechanism and means speeds.

A retaining point I arrange to run the machine at its amount of wear and tear dueto long move-l ments of the die or matrix case when runat I do this by putting actuating Any of the well known-vari-4 Ur; the front end of the main shaft f1 there a fixed pulley 168 adapted to be driven b a belt lll-1 at a compa atively slow rate of speed. is another fixed pulley 165 adapted to be driven by a belt 1136 at a higher or the maximum speed at which the machine can be run. Between these two tight or fixed pulleys there is a loose pulley 167. I have provided a shipper-bar 168, mounted in the front and rear walls of the column, which has lingers 188El engaging the belts 1641 and 186. The shipper-bar has rack teeth 169 cut' on its upper surface which engage a gear 170, loosely mounted on a shaft 171. This shaft has, on its left hand end, an arm 172 which is adapted to strike against pins 173 and 174 which project from the gear 170. The shaft 171 extends tothe right through the .side of the column which has aprojection or boss 175 at this point, and carries on. its outer end a gear 176 which is in mesh with a vertically sliding rack 177. By forcing this vertical rack down, the shipperbar 168 will be shifted so that the belt 164 will be on the tight. pnlley 108 and the'belt 166 will be carried on to the loose pulley 167 and the speed of the machine reduced thereby. its the slide 177 is returned to its nor mal position the arm 172 will be brought back to its position shown in Fig. 18 and that time the pm 17-1 will be in the po- Nsition shown dotted at 174 close up against.

" said arm.

By forcing the slide 177 upward reverse moveu'ient of the shipper-bar will be edected 'and the belts shifted back to the position shown in Fig. 12L The downward and upward movement of the bar 177 will be effected by means of a pair of slides 178 and 179 which are similar to the placer slides. rlhe slide 178 is connected by means of al link 180 to a lever 181. This lever has a roll 188 and is actuated by a cam surface ,nin is also drivena 182 on the cam wheel 100. A spring 184 serves to keep the roll 188 against the cam. A. reversing gear is interposed between the slides 17 8 and 179 so that they always move in opposite directions, as follows: The upper end of the slide 178 has 'rack teeth 185 and the slide 179 has a short rack 187 which slides in a slot 188 in the left side piece 46. Between the 'two racks is a reversing gear 186 so that, as the slide 178 is forced upward the slide 179 is driven downward. The slide 177 is provided with pins 189 similar to the selecting pins 59, etc. When any character to be selected which requires a long moi-ement in order to bring to the impression. point the proper actuating pins are setin one of the bars of the controller and in the bar jnst ahead of it the left hand l This pin causes one of the slides to drive the left hand selecting pin 183u of the slide 177, causing it to take downward movement with the lplacer A little farther back.

slide 179 and through the connections pointed out, to shift the belts and reduce the speed of the machine; so that when the next matrix character--the one which requires a long movement--is selected the machine will be ruiming slower. The next. adjacent pin of the controller (second from the left) is used to secure a reverse movement of the shipper-bar so as to secure the maximum speed.

This variable speed device is particularly valuable in type-casting and composing machines. Small type-those containing little met al`cool very much quicker than large sizes. at the maximum speed possible for ordinary sizes of a font, when a wide character was reachedsuch as ZE GE, the leader or even the cap M and l/V- there would not be sntlicient time for the metal to cool. By slowing down the movements for these wide characters, which may be done by the variable speed mechanism I have described, I am able to greatly increase the out-put of the machine. For this purpose the wide characters need not be located in outlying sections of the case, but.

may be put in any convenient or desied location.

What I claim is:

1. ln a power-driven matrix-selecting mechanism, adapted to secure the selection of matrices in the order of composition, means for securing a slow or retarded movement when matrices of thick or extended characters are being selected and means for securing accelerated or increased speed when matrices of thin l or condensed characters are being selected.
